When did American battleships start adding spotter aircraft?

American ships began adding them more regularly in the 1920s, with related experiments already appearing near the end of the First World War.

Adding a spotter aircraft to the hypothetical battleship raises a question about timing. American ships began carrying them more regularly in the 1920s, although related experiments were already appearing near the end of the First World War. This chronology makes aviation facilities plausible on a later modernization of a design begun in an earlier period. The exchange traces the move from experimental shipboard aviation to an expected capital-ship capability.
